Description

Method and node for handling the subscriber data updated

Technical field

The embodiments herein relate generally to the first mobile management node, the method in the first mobile management node, Method in second mobile management node and the second mobile management node.More specifically, the embodiments herein is related to processing The subscriber data of the renewal associated with user equipment (UE).

Background technology

Circuit switching (CS) standby (CSFB) and single radio continuous voice call (SRVCC) are in third generation cooperation group With the feature introduced in plan (3GPP) version 8.

CSFB in evolved packet system (EPS) makes it possible in UE by evolved universal terrestrial radio access network (E- Voice is provided when UTRAN) servicing by reusing CS infrastructure and other domains are serviced, i.e. using CS networks come with drilling for a long time Enter (LTE) network, i.e. packet switch (PS) network, voice service is provided together.The UE for being connected to E-UTRAN support CSFB can To be connected to CS domains using GERAN or UTRAN.This function only covers weight in E-UTRAN coverings by GERAN coverings or UTRAN It can be used in the case of folded.GERAN is the abbreviation of GSM EDGE radio access networks, and GSM is the contracting of global system for mobile communications Write, EDGE is the abbreviation of global evolution enhanced data rates, UTRAN is the abbreviation of universal terrestrial radio access network.Change Sentence is talked about, and CSFB is the mechanism that UE is moved to the legacy network for supporting audio call by LTE network.If many matchmakers of Internet Protocol Body subsystem (IMS) network is unavailable or UE can not be carried out (such as to the registration failure of IMS network) for some reason Voice (VoLTE) on LTE, then using CSFB.Term VoLTE is used to describe the voice and Short Message Service in LTE (SMS).Term legacy network is used to refer to any older network, the i.e. network older than current network, based on than current network The network of the old network standard of standard.

SRVCC is defined as " when UE only can be transmitted/connect on one in those access networks in preset time by 3GPP Time receiving, for the continuous voice call between the IMS on calling, the PS access that is anchored in IMS and CS accesses ". SRVCC is the processing in the CS domains that active voice call in wherein LTE is switched to legacy network.When UE is in the LTE areas of coverage There is active voice call and when UE removes LTE regions and enters only traditional network coverage in domain and on IMS, this may It is useful.It is dropped instead of calling, if supporting SRVCC, calling will be switched to CS legacy networks.

When UE can not be reached by such as PS networks, UE may be at suspended state or power down mode, or service movement Property management node for UE removed paging be marked (PPF) mark.When PPF is eliminated, its value can be set For "false" or it is arranged to the similar value that value 0 or cue mark are eliminated.When UE enters suspended state, mobile management section Point (for example, mobility management entity (MME) and/or Serving General Packet Radio Service Support Node (SGSN)) will be to gateway Node (such as gateway (SGW) and/or grouped data network gateway (PGW)) notifies the hang-up.When UE is in suspended state When, UE does not send any user data, and UE does not send any signaling information yet.When UE is in suspended state, because UE is in CS In service in domain, UE may service unavailable (UE or net for that can not carry out CS and PS simultaneously for PS in the ps domain Network).3GPP introduces power down mode in version 12.UE can enter power down mode on one's own initiative, and UE can be next Periodic Tracking Area, which wakes up when updating (TAU) message or next routing region updating (RAU) message or had in UE, appoints What uplink data or signaling wake up when transmitting.Indicate that information of the UE just into power down mode is not reported to such as SGW Or PGW gateway node.When UE does not reach (that is, non-reachable), it will not hear is sent to appointing for it by MME/SGSN What paging, and therefore will not reply.When UE enters power down mode, MME/SGSN is to preserve to be in power down mode on UE The only network node of information.According to existing demand, if MME/SGSN has been received by some network signals, this can be touched Other signalings of hair towards not reachable UE.It is considered from MME/SGSN towards other this signalings for not reaching UE It has failed.

The content of the invention

Therefore, the purpose of the embodiments herein is at least one eliminated in disadvantages mentioned above and provides the signaling of optimization.

According in a first aspect, the purpose is associated with UE more by being used for processing in a kind of first mobile management node The method of new subscriber data is realized.UE is currently that the first mobile management node is not accessibility.First mobile management Node receives the subscriber data of the renewal associated with UE from subscriber database.At least a portion of the subscriber data of renewal is repaiied Change.Mobile management node determines that the subscriber data updated should be postponed to the transmission of gateway node, until UE is changed into arriving Reach.

According to second aspect, the purpose is associated with UE more by being used for processing in a kind of second mobile management node The method of new subscriber data is realized.Second mobile management node determines that UE is had been changed to by the second mobile management node It is reachable.Second mobile management node receives from the first mobile management node and is transferred to gateway node on there is wait Renewal subscriber data information, and from subscriber database receive update subscriber data.The subscriber data of renewal is extremely A few part is changed.Second mobile management node transmits the subscriber data updated to gateway node.

The first mobility that subscriber data for handling the renewal associated with UE is passed through according to the third aspect, the purpose Management node is realized.UE is currently that the first mobile management node is not accessibility.First mobile management node is configured To receive the subscriber data of the renewal associated with UE from subscriber database.At least a portion of the subscriber data of renewal is repaiied Change.First mobile management node is configured to determine that the subscriber data of renewal should be postponed to the transmission of gateway node, directly It is changed into reachable to UE.

The second mobility that subscriber data for handling the renewal associated with UE is passed through according to fourth aspect, the purpose Management node is realized.Second mobile management node be used to determining UE has been changed to can be to by the second mobile management node Reach.Second mobile management node is configured as receiving from the first mobile management node is transferred to gateway on there is wait The information of the subscriber data of the renewal of node, and the subscriber data updated is received from subscriber database.The subscriber data of renewal At least a portion changed.Second mobile management node is configured as transmitting the subscriber data updated to gateway.

Because the transmission of the subscriber data of renewal is postponed until UE is reachable, i.e., until it can be with the first mobility pipe Node or the communication of the second mobile management node are managed, will success towards UE signaling from gateway.In other words, signaling is optimised.

The embodiments herein provides many advantages, wherein non exhaustive sample list is as follows：

The advantage of the embodiments herein is that they provide a kind of mechanism, (such as to be hung up when UE is not reached in UE When its PS is serviced, when UE enters battery saving mode, outside coverages of the UE in mobile management node and in mobility When PPF is eliminated in management node), avoid being considered as losing when receiving the subscriber data for the renewal initiated by subscriber database The extra signaling lost.The embodiments herein avoids other complexity, the wrong scene when extra signaling is rejected.

The embodiments herein can be related to subscriber server need update network in some nodes (such as MME, PGW, "Policy and Charging Rules Function (PCRF) etc.) in information.Because the transmission of the subscriber data of renewal is postponed until UE It is changed into reachable, the advantage of embodiment hereof is unlikely needs due to the unsuccessful result of processing by data storage (to retry) in scheduling request.

The embodiments herein is not limited to features described above and advantage.When reading described in detail below, those skilled in the art It will be recognized that additional feature and advantage.

When UE 101 has timed out its PS services, for example, when UE 101 is performed from E-UTRAN 201 to not supporting pair biographies During the GERAN 222 of defeated pattern (DTM) CSFB, UE 101 can not communicate with the network entity in PS core networks.This In the case of, initiate to be directed to the contexts of UE 101 or activity PDN connections by such as HSS 128 and PCRF 130 network entity Renewal be not it is optimal, movable PDN connections so trigger be considered as the signaling towards UE 101 of failure.

Above-mentioned DTM is applied to support GPRS UE 101.DTM is the agreement based on GSM standard, and it causes same radio Transmission is simpler while CS voices on channel and PS data.In the case of no DTM, UE 101 is allowed for while entering Row is received and transmitted.

The embodiments herein, which is provided, to be used for when UE 101 is not reached in mobile management node (such as UE 101 During into suspended state or in battery saving mode) mechanism of the transmission of processes user data.At least some in subscriber data can Be change subscriber data.

The signaling diagram described in Fig. 3 referring now to reference picture 1 describe according to some embodiments be used for handle with The method of the subscriber data of renewal associated UE 101.Fig. 3 is shown in which that UE 101 becomes as by first over time The accessibility embodiments of mobile management node 108a.Before method in figure 3 starts, i.e., before step 301 is performed, the One mobile management node 108a receives subscriber data for example during initial attachment from subscriber database 128.This is ordered User data can be referred to as QoS1.UE 101 and then effective operation load transmit and hang up its PS services, i.e. it is changed into arriving Reach.Method shown in Fig. 3 comprises the following steps, and these steps can also be with different from described below other suitable suitable Sequence is performed：

Step 301

First mobile management node 108a determines that UE 101 is not reached currently, i.e. the first mobile management node 108a can not now reach UE 101.Term currently can be with the current used interchangeably of term.First mobile management node 108a It can not yet be identified that returning to the first management node 108a, UE 101 does not pass for example, by detecting to the signalings transmitted of UE 101 Defeated any periodicity TAU message or UE, which are suspended etc., determines unattainability.In certain embodiments, the first mobility pipe Reason node 108a can be stored does not reach relevant information with UE 101.There may be UE 101 is the first mobile management section 108 not accessibility some reasons of point.One reason is probably that UE 101 is in suspended state.Other reasonses can be UE 101 Battery saving mode has been activated, or UE 101 is in outside the first mobile management node 108a radio coverage up to spy Fix time section, this may cause associated with UE 101 PPF in first mobile management node 108a etc. to be eliminated.

PPF will be now briefly described.UE 101 carries out periodicity TAU in idle mode.If UE 101 is without appointing What TAU or RAU, then the first mobile management node 108 may infer that UE 101 is not reached.However, the first mobile management Node 108a do not know UE 101 do not reach how long, therefore the first mobile management node 108a should not delete UE's immediately Carrying.On the contrary, the first mobile management node 108a should remove the PPF marks in the first mobile management node 108a, and And start implicit detach timer.Therefore, in remove state PPF can be described as to solution attachment UE 101 certain etc. Treat, and during the time, UE 101 will not be paged.

Step 302

Subscriber database 128 transmits the subscriber data updated, i.e. mobile management to the first mobile management node 108a Node 108a receives the subscriber data of the renewal associated with UE 101 from subscriber database 128.The subscriber data of renewal is extremely A few part is changed.The subscriber data of renewal can be referred to as QoS2.First mobility before starting with method in figure 3 The subscriber data QoS1 that management node 108a is received is compared, and the subscriber data QoS2 of renewal is updated.Subscriber database 128 can be with For example according to request, the subscriber data that transmission updates regularly or when data have updated.In certain embodiments, update Subscriber data at least a portion be modification subscriber data.The subscriber data of renewal can include for example associated with UE IMSI International Mobile Subscriber Identity (IMSI) and subscription data.The subscription data of renewal can include such as EPS subscribe to QoS (QCI, ARP) and subscribe to APN-AMBR.QCI is the abbreviation of QoS category identifiers, and ARP is distribution and the abbreviation for retaining priority, and And APN-AMBR is the abbreviation of APN-aggregate maximum bit rate.

Step 303

Because the first mobile management node 108a determines that UE is not reached in step 301, so the first mobility pipe Reason node 108a now determines that the transmission that should postpone the subscriber data of renewal to gateway node 110.This can be for example by first Mobile management node 108a is not reached currently based on identified UE 101 in step 301, is possibly also based in step Receive the subscriber data of renewal to determine from subscriber database 128 in rapid 302.The subscriber data of renewal should be postponed to gateway section The transmission of point 110, until UE 101 is changed into reachable, for example, is reached by the first mobile management node 108a.In some realities Apply in example, can be that the transmission of the part changed of subscriber data is delayed by.

Step 304

In certain embodiments, the first mobile management node 108a, which is set, indicates to pass to gateway node 110 in the presence of wait , that is, there is the subscriber data for waiting the renewal pending transmitted to gateway node 110 in the instruction of the subscriber data of defeated renewal.Make Mean that the subscriber data updated is received by the first mobile management node 108 with term " pending ", but data are also It is not further processed, i.e., it is not transmitted further to gateway node 110 also.

The instruction can be the form such as mark, information element (IE).More details on the instruction will later Description.

Step 305

First mobile management node 108a determines that UE 101 has been changed to reach, i.e. by the first mobile management section Point 108a is reached.This for example can be based on identified below by the first mobile management node 108：First mobile management node 108a pagings UE 101 simultaneously receives the response from UE 101, or the first mobile management node 108a notices that UE 101 is sent out TAU requests, RAU requests etc., or UE 101 has been sent to send service request etc..

Step 306

First mobile management node 108a transmits the subscriber data of the renewal pending of modification to gateway node 110 extremely A few part.If for example, parameter QCI, ARP and the APN-AMBR of subscription are changed, within step 306 to gateway section Point 110 transmits at least one in these parameters.The subscriber data transmitted within step 306 to gateway node 110 is changed Part can be described as Δ=QoS1-QoS2.Do not repaiied further, it is also possible to be transmitted within step 306 to gateway node 110 A part for the subscriber data of the renewal changed.Note, only as UE 101, have been changed to can by the first mobile management node 108a During arrival, the step 306 is just performed.Wherein UE 101 is described below with reference to Fig. 4 to have been changed to by the second mobile management section The accessibility embodiments of point 108b.

Step 307

When the part at least changed for the subscriber data that the transmission of warp-wise gateway node 110 updates, the first mobility Management node 108a can remove the instruction set in step 304, such as can remove mark.

The signaling diagram described in Fig. 4 referring now to reference picture 1 describe according to some embodiments be used for handle with The method of the subscriber data of renewal associated UE 101.Fig. 4 is shown in which that UE 101 becomes as by the over time, become The two accessibility embodiments of mobile management node 108b.This is different from the signaling diagram in Fig. 3, and Fig. 3 is shown in which UE 101 Become as by the first accessibility embodiments of mobile management node 108a.Before method in Fig. 4 starts, that is, performing step Before 401, the first mobile management node 108a for example receives user during initial attachment from customer data base 128 Data.The user data can be referred to as QoS1.Method shown in Fig. 4 comprises the following steps, these steps can also with Different other of description order suitable sequentially performs below：

Step 401

The step 301 that the step corresponds in Fig. 3.First mobile management node 108a determines that UE 101 can not currently be arrived Reach, i.e. the first mobile management node 108a can not now reach UE 101.First mobile management node 108a can pass through For example detect that the signaling transmitted to UE101 is not yet identified to return to the first management node 108a to be determined it.At some In embodiment, the first mobile management node 108a can be stored on the not accessibility information of UE 101.It there may be UE The 101 some reasons that can not be reached by the first mobile management node 108.One reason is probably that UE 101 is in hang-up shape State.Other reasonses be probably UE 101 be in the first mobile management node 108a radio coverage outside, UE 101 Battery saving mode or the PPF associated with UE 101 has been have activated to be eliminated in the first mobile management node 108a.

Step 402
